linux( sudo bmon ) 流量监控工具----类似于 moniter interface_monitor bandwidth interface eth1-优快云博客

本文介绍了如何在Linux系统中使用bmon工具监控网络接口的带宽使用情况。通过`sudo bmon`命令可以查看各接口的流量信息。bmon提供了一种类似moniter interface的监控方式，尤其在VyOS环境中，它被 VyOS 更改为 `moniter interface`，但其底层仍然是调用的bmon。此外，文章还展示了bmon的命令行选项及其用途，包括不同模块的配置和接口选择策略。

sudo bmon

monitor bandwidth interface eth0 （vyos 把 bmon 的linux 改为了 moniter interface 了，底层还是调用的 bmon）

Linux:~$ sudo bmon -h

Usage: bmon [OPTION]...

Options:
Startup:
-i, --input=MODPARM Input module(s)
-o, --output=MODPARM Output module(s)
-f, --configfile=PATH Alternative path to configuration file
-h, --help Show this help text
-V, --version Show version

Input:
-p, --policy=POLICY Element display policy (see below)
-a, --show-all Show all elements (even disabled elements)
-r, --read-interval=FLOAT Read interval in seconds (float)
-R, --rate-interval=FLOAT Rate interval in seconds (float)
-s, --sleep-interval=FLOAT Sleep time in seconds (float)
-L, --lifetime=LIFETIME Lifetime of an element in seconds (float)

Output:
-U, --use-si Use SI units
-b, --use-bit Display in bits instead of bytes

Module configuration:
modparm := MODULE:optlist,MODULE:optlist,...
optlist := option;option;...
option := TYPE[=VALUE]

Examples:
-o curses:ngraph=2
-o list # Shows a list of available modules
-o curses:help # Shows a help text for html module

Interface selection:
